Description

Technical Field

[0001] This application relates to the field of product assembly technology, and in particular to a snap-fit ​​structure. Background Technology

[0002] Many electronic products are often designed with a snap-fit ​​structure that includes a cover and a main body. The cover is used to seal the inner cavity of the main body or cover a certain area of ​​the main body to protect the electronic components located inside or on the main body.

[0003] In related technologies, the cover plate and the product body are usually detachably connected by a snap-fit ​​connection, which facilitates disassembly and installation. However, in existing snap-fit ​​structures, when assembling the cover plate onto the product body, force is usually applied to snap the cover plate onto the product body to fix the cover plate and the product body together; when removing the cover plate from the product body, tools such as pry bars are usually used to forcefully pry the cover plate open. This can easily lead to breakage of the connection between the cover plate and the product body, and pry bars and other tools can also easily cause scratches on the surface of the product. Utility Model Content

[0004] Based on this, and in view of the shortcomings of the existing locking structure, this application provides a locking structure to solve the above-mentioned problems of the existing locking structure.

[0005] According to one aspect of this application, a snap-fit ​​structure is provided, including a cover plate, a body, and a first snap-fit ​​assembly and a snap-fit ​​assembly capable of detaching and attaching the cover plate relative to the body.

[0006] The snap-fit ​​assembly has an assembled state and a disassembled state:

[0007] When the snap-fit ​​assembly is in the separated state, the cover plate is located in the first position, and the first snap-fit ​​assembly is in the separated state, with the cover plate tilted relative to the main body;

[0008] When the snap-fit ​​assembly is in the assembled state, the cover plate is located in the second position, and the first snap-fit ​​assembly is in the assembled state, with one side surface of the cover plate flush with at least a portion of the outer surface of the body.

[0009] In one embodiment, the snap-fit ​​assembly includes a hook and a guide bar, one of which is disposed on the cover plate and the other on the main body; the hook is slidable along the guide bar to switch the cover plate between a first position and a second position;

[0010] When the cover plate is in the first position, the hook is misaligned with the guide strip; when the cover plate is in the second position, the hook engages with the guide strip.

[0011] In one embodiment, the hook has a snap-fit ​​surface, the guide strip has a guide surface, and the snap-fit ​​surface is slidable along the guide surface.

[0012] In one embodiment, the guide surface includes a first guide surface extending along a first direction and a second guide surface inclined relative to the first guide surface, the second guide surface being connected to one end of the first guide surface along the first direction; the snap-fit ​​surface is capable of sliding contact with the second guide surface and the first guide surface in sequence, so that the cover plate can move between the first position and the second position;

[0013] When the snap-fit ​​surface slides along the second guide surface, the cover plate slides at an angle relative to the main body; when the snap-fit ​​surface slides along the first guide surface, the cover plate slides relative to the main body along the first direction.

[0014] In one embodiment, the snap-fit ​​surface includes a first snap-fit ​​surface extending along the first direction and a second snap-fit ​​surface inclined relative to the first snap-fit ​​surface, the second snap-fit ​​surface being connected to one end of the first snap-fit ​​surface along the first direction; when the cover plate is in the second position, the first snap-fit ​​surface is attached to the first guide surface, and the second snap-fit ​​surface is attached to the second guide surface.

[0015] In one embodiment, the first engaging assembly includes a first engaging member disposed on one of the cover plate and the main body, and the other of the cover plate and the main body has a slot; when the first engaging assembly is in an assembled state, the first engaging member is engaged in the slot, and when the first engaging assembly is in a disassembled state, the first engaging member is located outside the slot.

[0016] In one embodiment, the first engaging member has a locking connector that is interference-fitted with the locking slot.

[0017] In one embodiment, the cover plate is capable of producing a recoverable bending deformation as it moves between the first position and the second position.

[0018] In one embodiment, the engaging structure further includes a second engaging component; when the cover plate is in the first position, the second engaging component is in a disengaged state, and when the cover plate is in the second position, the second engaging component is in an assembled state.

[0019] In one embodiment, the second engaging assembly includes a second engaging member disposed on one of the cover plate and the body, the other of the cover plate and the body having a guide groove with an opening; as the cover plate moves from the first position to the second position, the second engaging member can engage into the guide groove from the opening.

[0020] The aforementioned locking structure, by providing a first locking component and a locking assembly that allow the cover plate to be detached from the main body, and by having the locking assembly in an assembled state and a disassembled state, allows the cover plate to be in a first position when the locking assembly is in the disassembled state, and the locking assembly is in the disassembled state, at which time the cover plate is tilted relative to the main body; when the locking assembly is in the assembled state, the cover plate is in a second position, and the first locking assembly is in the assembled state; at this time, one side surface of the cover plate is flush with at least part of the outer surface of the main body, so when the cover plate and the main body are connected or disassembled, there is no need to force the cover plate and the main body to lock together, nor is there a need to use a pry bar to forcibly pry the cover plate open, thereby not only avoiding breakage of the locking assembly, but also avoiding scratching the product surface with a pry bar.

Detailed Implementation

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0043] See Figure 1 and Figure 2 This application provides a snap-fit ​​structure 10, which can be in an assembled state or a disassembled state. Figure 1 A schematic diagram of the engaging structure 10 in the assembled state is shown. Figure 2 A schematic diagram of the engaging structure 10 in a disassembled state is shown. The engaging structure 10 provided in the embodiments of this application includes a cover plate 100 and a main body 200. The cover plate 100 is detachably connected to the main body 200. In one embodiment, when the cover plate 100 is assembled on the main body 200, the cover plate 100 and the main body 200 together form the outer shell of the speaker, and the cover plate 100 can cover a part of the main body 200 to protect the components disposed on the main body 200.

[0044] It is understood that in other embodiments, the snap-fit ​​structure 10 of this application is not limited to the outer shell of the speaker, but can also be composed of any parts that need to be assembled with each other, and is not limited here.

[0045] Specifically, such as Figure 3 As shown, the main body 200 includes a bracket 210 and a bracket shell 220. The bracket 210 is annular, and the bracket shell 220 covers the bracket 210 to form the inner cavity of the speaker together with the bracket 210. The cover plate 100 can be detachably connected to the bracket 210 to form the outer shell of the speaker together with the bracket shell 220.

[0046] More specifically, in a preferred embodiment, a groove 211 is formed on one outer surface of the bracket 210, and the bracket shell 220 is attached to the bracket 210 except for the part with the groove 211 to form the outer surface of the main body 200. When the cover plate 100 is assembled on the main body 200, the cover plate 100 completely covers the groove 211, so that one side surface of the cover plate 100 is flush with the outer side surface of the main body 200, thereby making the overall appearance of the speaker shell more aesthetically pleasing.

[0047] Regarding the connection between the cover plate 100 and the main body 200, the cover plate 100 is detachably installed on the main body 200 by a snap-fit ​​connection. However, as described in the background art, when assembling the cover plate 100 onto the product main body 200 using the existing snap-fit ​​structure 10, the cover plate 100 is usually snapped onto the product main body 200 by force to fix the cover plate 100 and the product main body 200 to each other. When removing the cover plate 100 from the product main body 200, tools such as pry bars are usually used to forcefully pry open the cover plate 100. This can easily cause the connection between the cover plate 100 and the product main body 200 to break, and tools such as pry bars can also easily cause scratches on the surface of the product.

[0048] To solve the above problems, such as Figure 4 and Figure 5 As shown, the engaging structure 10 provided in this application further includes a first engaging component 300 and a engaging component 400 that enable the cover plate 100 and the main body 200 to be disassembled and assembled. The engaging component 400 has an assembled state and a disassembled state, so that the cover plate 100 can be located in a first position or a second position. When the engaging component 400 is in the disassembled state, the cover plate 100 is located in the first position, and the first engaging component 300 is in the disassembled state. The cover plate 100 is inclined relative to the main body 200. At this time, the cover plate 100 and the main body 200 are disassembled from each other. When the engaging component 400 is in the assembled state, the cover plate 100 is located in the second position, and the first engaging component 300 is in the assembled state. The cover plate 100 completely covers the groove 211 opened on the main body 200. At this time, one side surface of the cover plate 100 is flush with at least a part of the surface of the main body 200. Thus, there is no need to forcibly attach the cover plate 100 to the main body 200, nor is it necessary to use a pry bar to forcibly remove the cover plate 100 from the main body 200.

[0049] Specifically, see Figure 6 The snap-fit ​​assembly 400 includes a snap hook 410 and a guide strip 420. The snap hook 410 is disposed on the cover plate 100, and the guide strip 420 is disposed on the main body 200, for example, on the bracket 210 of the main body 200. The snap hook 410 is slidable along the guide strip 420 to switch the cover plate 100 between a first position and a second position. Specifically, the snap hook 410 is hook-shaped and has a snap-fit ​​surface 411 facing the guide strip 420, and the guide strip 420 has a guide surface 421 facing the snap-fit ​​surface 411, such as... Figure 7 As shown, the snap-fit ​​surface 411 can conform to the guide surface 421 and slide along the guide surface 421 in the first direction (i.e., the X direction shown in the figure). Figure 6 As shown, when the cover plate 100 is in the first position, the hook 410 and the guide strip 420 are misaligned, and at this time, the snap-fit ​​assembly 400 is separated; as Figure 7As shown, when the cover plate 100 is in the second position, the hook 410 is engaged with the guide bar 420. At this time, the engaging component 400 is engaged, and the displacement of the hook 410 along the third direction (Z direction shown in the figure) is limited by the guide bar 420.

[0050] See Figure 3 In the embodiment shown in the figure, hooks 410 are disposed on the two opposite edges of the cover plate 100 facing the main body 200 and along the second direction (i.e., the Y direction shown in the figure). Guide strips 420 are disposed in the groove 211 opened in the main body 200 near the side wall of the groove 211, corresponding to the hooks 410. In the first direction, there are multiple hooks 410 and multiple guide strips 420, which are spaced apart along the first direction, with each hook 410 corresponding to a specific guide strip 420. Of course, the number of hooks 410 and guide strips 420 is not limited and can be set as needed. Furthermore, in some other embodiments, hooks 410 can be disposed on the main body 200, and guide strips 420 can be disposed on the cover plate 100; the specific arrangement is not limited.

[0051] See Figure 8 and Figure 9 In one embodiment, the first engaging assembly 300 includes a first engaging member 310 and a first engaged member 320. The first engaging member 310 is disposed on the side of the cover plate 100 facing the main body 200, and the first engaged member 320 is installed in a groove 211 opened in the bracket 210 of the main body 200, and the first engaged member 320 has a slot 321. When the first engaging assembly 300 is in the assembled state, that is, when the cover plate 100 is in the second position, the first engaging member 310 is engaged in the slot 321, so that the first engaging assembly 300 is assembled and connected. At this time, the cover plate 100 completely covers the groove 211 and is completely fixedly connected to the main body 200. When the first engaging assembly 300 is in the separated state, that is, when the cover plate 100 is in the first position, the first engaging member 310 is located outside the slot 321, so that the first engaging assembly 300 is separated.

[0052] Similarly, in some other embodiments, the first engaging member 310 may be disposed on the main body 200, and the first engaged member 320 may be disposed on the cover plate 100. It can also be understood that when the first engaging member 310 is disposed on the cover plate 100, the slot 321 may be directly formed on the main body 200; when the first engaging member 310 is disposed on the main body 200, the slot 321 may be directly formed on the cover plate 100, and this is not limited here.

[0053] For the structure of the first card assembly 310, please refer to [link / reference needed]. Figure 8 and Figure 9The first engaging component 310 includes a locking post 311 and a locking connector 312. The locking connector 312 is connected to one end of the locking post 311. When the first engaging component 310 is disposed on the cover plate 100, the end of the locking post 311 away from the locking connector 312 is connected to the cover plate 100. When the first engaging component 310 is disposed on the main body 200, the end of the locking post 311 away from the locking connector 312 is connected to the main body 200. The locking connector 312 can be interference-fitted with the locking groove 321 so that the first engaging component 310 and the first engaged component 320 can be connected to each other, thereby putting the first engaging assembly 300 in an assembled state. Specifically, the diameter of the locking connector 312 is larger than the diameter of the locking post 311, and the diameter of the locking connector 312 is larger than the groove diameter. The snap-fit ​​connector 312 is made of an elastic material. When the first snap-fit ​​member 310 is snapped into the slot 321, the snap-fit ​​connector 312 can undergo recoverable deformation under the pressure of the slot wall of the slot 321, allowing the snap-fit ​​connector 312 to pass through the slot 321. Thus, under small external forces, the snap-fit ​​connector 312 will interfere with the slot wall of the slot 321, preventing the snap-fit ​​connector 312 from passing through and disengaging from the slot 321. Only by applying a large force can the snap-fit ​​connector 312 pass through and disengage from the slot 321, thereby ensuring that the first snap-fit ​​member 310 is securely snapped into the slot 321.

[0054] It is worth noting that, since the first engaging member 310 protrudes relative to the cover plate 100 or relative to the main body 200, when the hook 410 and the guide block slide relative to each other, the first engaging member 310 may interfere with the main body 200 when it is connected to the cover plate 100.

[0055] Therefore, to avoid interference between the first engaging member 310 and the cover plate 100 or the main body 200, the cover plate 100 is designed to be relatively thin, and is made of a metal material or other material capable of elastic deformation. Thus, when the cover plate 100 moves between the first and second positions, it can undergo recoverable bending deformation, allowing it to avoid the main body 200 when the first engaging member 310 is on the cover plate 100, and to avoid the cover plate 100 when it is on the main body 200. When the cover plate 100 moves to the second position, the bending deformation disappears, and the cover plate 100 completely covers the groove 211, ensuring that the cover plate 100 can smoothly move to the second position by sliding relative to the hook 410 and the guide strip 420.

[0056] Furthermore, because of the presence of the first engaging member 310 and the groove 211 formed on the main body 200, in order to avoid the first engaging member 310 and to ensure that the cover plate 100 can avoid the edge of the groove 211 when moving from the first position to the second position, the hook 410 and the guide block can smoothly change from a misaligned state to a mutually engaging state. Preferably, as Figure 6 As shown, the guide surface 421 on the guide block includes a first guide surface 421a extending along a first direction and a second guide surface 421b inclined relative to the first guide surface 421a. The second guide surface 421b is connected to one end of the first guide surface 421a along the first direction. The engaging surface 411 can slide in contact with the second guide surface 421b and the first guide surface 421a in sequence, so that the cover plate 100 can move between a first position and a second position. When the engaging surface 411 slides along the second guide surface 421b, the cover plate 100 slides inclined relative to the main body 200. When the engaging surface 411 slides along the first guide surface 421a, the cover plate 100 slides relative to the main body 200 along the first direction.

[0057] By setting a second guide surface 421b that is inclined relative to the first guide surface 421a, such that... Figure 10 As shown, the cover plate 100 can be slightly tilted relative to the main body 200, so that, Figure 11 As shown, the engaging surface 411 can first contact the second guide surface 421b and slide a certain distance, so that the hook 410 and the guide bar 420 change from a misaligned state to a engaged state, and then... Figure 7 As shown, the snap-fit ​​surface 411 then contacts the first guide surface 421a and continues to slide along the first direction, causing the cover plate 100 to move into the second position, thus successfully completing the snap-fit ​​between the hook 410 and the guide strip 420. Conversely, when it is necessary to remove the cover plate 100 from the main body 200, the snap-fit ​​surface 411 can slide a distance in the opposite direction relative to the first guide surface 421a along the first horizontal direction, and then the snap-fit ​​surface 411 can move a distance in the opposite direction along the inclined second guide surface 421b. At this time, the cover plate 100 can be taken out from the groove 211 at a slight inclination relative to the main body 200, thereby ensuring that the first snap-fit ​​component 310 can be used to more easily assemble or disassemble the cover plate 100 with the main body 200 without interference.

[0058] Furthermore, after the cover plate 100 has moved into place, in order to limit the movement of the cover plate 100, please refer to [further details]. Figure 6The latching surface 411 on the latch 410 includes a first latching surface 411a extending along a first direction and a second latching surface 411b inclined relative to the first latching surface 411a. The second latching surface 411b is connected to one end of the first latching surface 411a along the first direction. When the cover plate 100 is latched in place and in the second position, the horizontally arranged first latching surface 411a is attached to the horizontally arranged first guide surface 421a, and the inclined second latching surface 411b is attached to the inclined second guide surface 421b. In this way, the second guide surface 421b can block the second latching surface 411b, thereby preventing the cover plate 100 from continuing to move along the first direction.

[0059] See Figure 4 and Figure 5 In order to make the cover plate 100 more securely engaged with the main body 200, as a further improvement, the engaging structure 10 also includes a second engaging component 500 disposed between the cover plate 100 and the main body 200. The second engaging component 500 is disposed at a distance from the first engaging component 300. When the cover plate 100 is in the first position, the second engaging component 500 is also assembled and connected, so that after the cover plate 100 is assembled with the main body 200, both ends of the cover plate 100 along the first direction can also be securely connected to the main body 200.

[0060] The specific structure of the second card-closing component 500 is similar to that of the first card-closing component 300, such as... Figure 12 and Figure 13 As shown, the second engaging assembly 500 includes a second engaging member 510 and a second engaged member 520. The second engaging member 510 is also disposed on the side of the cover plate 100 facing the main body 200. The second engaged member 520 is also installed in the groove 211 opened in the bracket 210 of the main body 200, and the second engaged member 520 is also provided with a guide groove 521. Unlike the first engaging assembly 300, one end of the guide groove 521 has an opening that connects to the guide groove 521. During the movement of the cover plate 100 from the first position to the second position, the second engaging member 510 can be guided by the opening to engage into the guide groove 521, so that the second engaging assembly 500 is assembled and connected. Conversely, during the movement of the cover plate 100 from the second position to the first position, the second engaging member 510 can be guided by the opening to leave the guide groove 521, so that the second engaging assembly 500 is separated. This eliminates the need to forcefully assemble or separate the second engaging assembly 500.

[0061] The specific structure of the second card assembly 510 is similar to that of the first card assembly 310, and will not be described in detail here.

[0062] Similarly, it is understandable that the second latching member 510 can be disposed on the main body 200, and the second latched member 520 can be disposed on the cover plate 100. It is also understandable that when the second latching member 510 is disposed on the cover plate 100, the guide groove 521 can be directly formed on the main body 200; when the first latching member 310 is disposed on the main body 200, the latching slot 321 can be directly formed on the cover plate 100, and no limitation is made here.

[0063] The snap-fit ​​structure 10 provided in this application has the following complete operation flow when the cover plate 100 needs to be assembled onto the main body 200:

[0064] First, such as Figure 10 As shown, the cover plate 100 is inserted into the groove 211 at a certain angle. During assembly, the cover plate 100 needs to be slightly bent and deformed, and then along... Figure 10 Pushing the cover plate 100 in the X direction to the second position causes the hook 410 to slide relative to the guide block until it becomes Figure 7 In the middle state, the latch 410 and the guide block are engaged, so that the latching assembly 400 is assembled and engaged, and at the same time... Figure 13 As shown, the second engaging component 510 is also engaged into the guide groove 521 through the opening of the guide groove 521, so that the second engaging component 500 is assembled and fitted.

[0065] Then, as Figure 14 As shown, along Figure 14 The Z+ direction presses the cover plate 100, causing the first engaging member 310 to engage in the slot 321, thereby assembling and fitting the first engaging assembly 300.

[0066] When it is necessary to remove the cover plate 100 from the main body 200, the complete operation procedure is as follows:

[0067] First, use a suction cup to pick up one end of the cover plate 100, such as... Figure 14 As shown, apply slight force to pull the first engaging member 310 out of the slot 321 along the Z-direction, thereby separating the first engaging assembly 300.

[0068] Then, the cover plate 100 is moved diagonally in the opposite direction. At this time, the hook 410 disengages from the guide block, causing the locking assembly 400 to separate. At the same time, the second locking member 510 moves out of the guide groove 521 from the opening of the guide groove 521, causing the second locking assembly 500 to also separate.

[0069] Finally, the cover plate 100 is completely removed from the groove 211 at an angle, thus completing the removal of the cover plate 100 from the main body 200.

[0070] Therefore, when the cover plate 100 is assembled onto the main body 200 using the snap-fit ​​structure 10 of this application, or when the cover plate 100 is removed from the main body 200, the snap-fit ​​component 400 and the second snap-fit ​​component 500 are slidably snapped or separated by a guide. In this way, there is no need to force the cover plate 100 and the main body 200 to snap together, nor is there a need to use a pry bar to forcefully pry open the cover plate 100. This not only avoids the breakage of the snap-fit ​​hook 410 of the snap-fit ​​component 400, but also avoids scratching the product surface with a pry bar.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
